Port --without-x --enable-gcc-warnings to Fedora 19.

* configure.ac (WERROR_CFLAGS): Omit redundant use of
-Wmissing-field-initializers, -Wswitch, -Wtype-limits,
-Wunused-parameter.  If there is no window system, also omit
-Wsuggest-attribute=const and -Wsuggest-attribute=noreturn; this
is needed for Fedora 19.
* src/gfilenotify.c (globals_of_gfilenotify):
Call g_type_init only if using an older glib version that needs it.
